Non-isothermal dehydration kinetic study of aspartame hemihydrate using DSC, TGA and DSC-FTIR microspectroscopy

Study on biodegradation process of lignin by FTIR and DSC.

The biodegradation process of lignin by Penicillium simplicissimum was studied to reveal the lignin biodegradation mechanisms. The biodegradation products of lignin were detected using Fourier transform infrared spectroscopy (FTIR), UV-Vis spectrophotometer, different scanning calorimeter (DSC), and stereoscopic microscope. The analysis of FTIR spectrum showed the cleavage of various ether link...

Interpreting DSC curves; Part 2: Isothermal measurements

J. Widmann Dear Customer UserCom is becoming more and more popular. In the last edition, we made a number of improvements to the layout and have now decided to print a Spanish version in addition to the English, German and French editions. On the last page, we would like to introduce the METTLER TOLEDO editorial team. The name of the author is now noted along with the title of each article. Inf...

Modulated Dsc Evaluation of Isothermal Cure & Vitrification for Thermosetting Systems

DSC-FTIR microspectroscopy used to investigate the heat-induced intramolecular cyclic anhydride formation between Eudragit E and PVA copolymer

INTRODUCTION Acrylic resins containing acrylic acid (AA), methyl methacrylate (MMA) or acrylic–methacrylic copolymer are the most commonly used polymeric materials for biomedical and pharmaceutical applications owing to their hydrophilicity and biocompatibility.1–4 Recently, a new polyvinyl alcohol (PVA) copolymer designed by copolymerizing AA and MMA with PVA was successfully developed as a ca...

DSC Study of Collagen in Disc Disease

Differential scanning calorimetry (DSC) has been used to estimate the effect of disc disease on the collagen helix-coil transition and morphology for tissue extracted from patients during surgical operation. Forty discs were obtained from patients with degenerative disc disease undergoing surgery for low back pain. The patients were in the age between 20 and 70 years old. The specimens were kep...
